TL;DR
This study develops and validates a seated-style echocardiography robot that allows safe, effective cardiac imaging in sitting posture, with mechanisms to reduce physical burden and maintain diagnostic quality.
Contribution
The paper introduces a novel seated echocardiography robot with mechanisms to reduce physical load and demonstrates its feasibility for cardiac diagnosis in sitting posture.
Findings
Diagnostic views comparable to conventional exams were obtained.
Body burden increased with lateral bending angle.
Load reduction mechanisms effectively decreased physical load.
Abstract
Purpose: Conventional robotic ultrasound systems were utilized with patients in supine positions. Meanwhile, the limitation of the systems is that it is difficult to evacuate the patients in case of emergency (e.g., patient discomfort and system failure) because the patients are restricted between the robot system and bed. Then, it is ideal that the patient undergoes the examination in the sitting position in terms of safety. Therefore, we validated a feasibility study of seated-style echocardiography using a robot. Method: Preliminary experiments were conducted to verify the following two points: (1) the possibility of obtaining cardiac disease features in the sitting posture as well as in the conventional examination, and (2) the relationship between posture angle and physical burden. For reducing the physical burden, two unique mechanisms were incorporated into the system: (1) a leg…
